To all whom t may-concern Be it known that I, WILLIAM'E. C oivGDoN, a citizen of the United States, residing` at West Chester, inthe county of Chester and 5 State of Pennsylvania, have.

invented cer- Improvements 1n Bagtain new and-useful following 1s a speclca- Locks, of which the tion.

My invention relates improvements in buttons to new and useful andmore particularly to a button adapted for use on an automobile pocket or similar device employing a fiap for closing the same.

The primary object of the invention is the construction of such a button which may be locked in position whereby it cannot be operated by an unauthorized person.

A further object of the invention is the provision of a button of simple construction in which the parts are easily assembled and operated. y

A still further object of the invention is the construction of a button adapted to be secured to the underside of the iap whereby it is impossible to manipulate the same except by inserting a key for unlocking.

With these and other` objects in view the invention consists in the novel details of construction and arrangement of y parts the following description and drawings, in which, 1

Figure 1 is a plan view showing the'stud of the button. Fig. 2 is a face view of the button plate showing the key opening. Fig. 3 is a` longitudinal vertical section on the line 3-3 of Fig..1. Fig. 4 is a transverse vertical section on the linea- 4 of Fig. 1. Fig. 5 is. a transverse section on the line 5-5 of Fig. 41. Fig. 6 is a detail of the key guide. Fig. 7 is a Fig. 8 is a top-plan view showing the button in locked position.

My improved button is primarily adapted'- for locking a`iap to the body of a receptacle and as ordinarily c onstructed the button isA secured to the receptacle and passesthrough in the iiap. By this arrangement access 1s gained to the button which extends through theeye. I have overcome this ob-v jection by lconstructing a button which is' adapted to be secured to the flap and pass l through an eye in the receptacle. Bythis construction the locking parts of the button- 5.5

are held `within Ythe receptacle and access which will be more clearly understood from of and are adapted formed in the plug 7 detail. of the key, and

will be laterv set (which is adapted to enter cannot be gained thereto without first unv locking the several parts.

In carrying out my invention Iprovide a plate' 1 which `is adapted to be secured to a flap in any suitable manner but preferably by means of rivets passing through the openings 2 and through the flap. The plate has a projection 3 formed thereon and a central bore is formed through the plate and projection. At the endof the projection is formed a circumferential flange 4 which overlies the central bore and the purpose of which willbe presently described. The fiange l is .of sucha width as to leave a central opening therethrough of less diameter than the central bore through the projection 3.

A sleeve 5 is received within the central bore through the plate and `projection and said sleeve is provided on the outer end with an enlargement or bead, indicated at 6. The sleeve is provided with `a plurality of vertically spaced openings, the purpose of which will be presently described. Within the sleeve is a plug 7 having a plurality of transverse openings therethrough as more clearly shown in Figs. 3 and 5 of the drawings. Operating in the transverse openings are thepin tumblers 8 which are pressed forward by means4 of the springs 9 which operate between the sleeve 5' and ends of the tumblers 8. The'ends are adapted to extend through the vertically spaced/openings in the sleeve 5, Figs. 3 and 5 of the drawings. A slot 10 is cut in the pin tumblers 8 lnear one end thereto receive the key for A longitudinal bore is and is adapted to receive the key guide 11 shownin detail in Fig. 6 of the drawings.- This key guide is provided with a slot 12 into which the key is adapted to be inserted and is formed with the cutaway portions 13 which engage around the pin tumblers 8.

A slot 14: is formed in the projection 3 ad!v jacent the central bore andis adapted to receive the ends' of the pin tumblers 8 when the button is in locked position and which forth in detail. A projection y-15 is formedonthe inner end of the plug 7 and received upon the extension is a operating the' bolts.

' casting or'button member 16 provided on the a circumferential flange 17 a circumferential inner face with of the tumblers as shown 1n groove formed in the end of the projection The button member is of-.the shape shown in Figs. 3 and 4 of the drawings, and the end of the projection l5 is flared, as shown at 18, to secure the 'button 16 upon the projection.

A` corrugated spring plate 19 encircles the projection -15 and is flange 4 and the end of the plug 7. This sprlng holds the projection 17 on the button 16 in the groove 1n the end of the projection 3 at all times. I

A key, is indicated at 20, for operating the pin tumblers 8 but I wish it distinctly understood that I do not limit myself to this particular shape of key as it will be necessary to vary in shape so as to change each lock whereby only one key will operate a lock. The projection 3 and the button 16 .advantages and operation will be clearly undraw the tumblers.

unlock thebutton the key is inserted into derstood. As indicated in Figs. 1, 3, 4 and 5, the button is in its unlocked position ready to be inserted through the elliptical opening in the plate tion passes through the beaded ends 6 of the sleeve 5 is engaged by the fingers and the sleeve rotated thereby rotating the elliptical button 16 so that it eX- tends beyond the sides of the projection 3 i clearly and engages the plate 21, as more shown in Fig. 8 of the drawings. The pin tumblers 8 will enter Ithe slot 14 and the button is then locked and cannot be removed Without inserting a key to with- When it is desired to the slot 12 formed in the key guide 11 and engages the slots 10 formedinAv the endsof the. pin tumblers. By turning thev key the tumblers are withdrawn .from the slot 14 and the sleeve can then be turned to bring the casting 4or button 16 into alinement with A the projection 3.' The members can then be withdrawn through the -eye of the plate 21 and the flapy opened to gain access to the receptacle.

In'considering the advantages of my device it must be remembered that the button is secured'to the flap and no parts are accessiblek until the flap is opened and when in locked position it isimpossible to manipulate the several parts without first inserting the key for withdrawing the tumblers.

Having fully described'the invention what aim as new and desire to secure by Let-r ters Patent is 1. A button comprising a stationary projection having received. between the l21. When theprojecfy the elliptical opening p a central bore therethroughl and av slot adjacent the bore, a sleeve rotatably mounted in the bore and having a plurality of spaced openings, a plug mounted in the sleeve and provided with a plurality of transverse openings,` and a longitudinal opening in communication with the transverse openings, tumblers having slots formed therein slidably mounted in the transverse openings and through the openings in the sleeve, a key guide rotatably mounted within the longitudinal opening and provided with cutaway portions adaptedto receive the pin tumblers, a key adapted to be received in the key guide and engage the slots in the tumblers, anda head secured tothe plug. v v
